Notes: 1. The converter output voltage shall be stable when (13,200µF total) tantalum low ESR filter capacitors are connected across the output of the converter.
2. For 3.43 Input Voltage Rail having IOmax = 40A, the minimum input filter capacitor required is 6600µF (use multiple 330µF tantalum capacitor having 60mΩ ESR.)
3. For 5.00 Input Voltage Rail having IOmax = 55A, the minimum input filter capacitor required is 3960µF (use multiple 330µF tantalum capacitor having 60mΩ ESR.)

Application Notes
Control Signals
Control Signal Characteristics: Per Table on Page 4.
Trim: The output voltage may be lowered from the nominal
programmed value by adding an external resistor from the TRIM
pin (J1-10) to – Sense (J1-1). This is used to obtain output voltages
between the programmed values. The maximum value the output
may be trimmed is approximately –4.5% of Vprog. The resistor
value may be calculated from the following formula:
Enable_H: This input signal is used to enable the output of the
converter when activated (active High). The signal is referenced to
either the output side (-Sense) or GND. It has an internal pull-up
resistor. To disable the converter requires an open collector logic
signal to pull it down.
(2490) (Vtrim)
4 Bit Logic Signals: The state of the 4 bit control signals controls
the output voltage. Normally, the 4 bits are in a ‘low state’ and
provide for a 2.5V output voltage. The output voltage may be
programmed between 1.429 to 2.5V by setting appropriate logic
bits ‘high’ through D0, D1, D2, and D3.
Rext = ––––––––––––––––––– - 15000
(3.49) (Vprog – Vtrim)
Vtrim = Desired output voltage with Rext tied from TRIM pin to
– SENSE.
Vprog = Nominal programmed output voltage
Powergood_H: The Powergood signal is in a ‘high’ state when the
output voltage is within +/- 7.5% of the output voltage programmed
by the 4 logic bit inputs.
Notes: 1. Vtrim must be less than Vprog.
2. The trim pin does not change the OVP or Powergood_H trip
points. These are set by the 4 bit logic inputs
OVPFault_H: This signal is in a ‘high’ state when the output
voltage is greater than +/-15% of the output voltage programmed by
the 4 bit logic inputs or exceeds the maximum operating
temperature of the converter. This output is the open emitter of a
transistor which pulls to +5V in the high state and is open in the
low state. For driving logic, an appropriate pull down resistor from
OVPFault_H to – Sense is required. The OVPFault_H is asserted
high when OVPFault is activated. When driving an SCR to ‘crow-
bar’ the input source from a Fault_H signal, use the circuit below:
